  1. Abdominal obesity = Waist to height ratio > =0.5; High TG = TG > 100; Low HDL = HDL-C < 40 mg/dl except in boy 15-19y; high systolic BP = SBP at or above the 90th for age, gender and height; high diastolic BP = DBP at or above the 90th for age, gender and height; High BP = either high SBP / DBP at or above the 90th for age, gender and height; Metabolic syndrome = defined according to ATP-III criteria; SBP Systolic blood pressure, DBP Diastolic blood pressure, FBG Fasting blood sugar, TG Triglycerides, HDL High density cholesterol
